We probably did, and I forgot where we landed.

So, without previous recollection... the rdap-bootstrap case can be used when a 
bootstrap server has other redirect behavior. For example, it is possible that 
a bootstrap server can construct its redirects from the NRO extended stats 
files thus offering clients a direct path to the server holding the resource 
instead of bouncing between RIRs. And there are other example I can think 
about, such as a bootstrap server that offers IP to ASN mapped redirects. All 
this is to say that "rdap-bootstrap" is a way for the client to say "I want the 
9224 redirect".

It also allows a typical resource server to function as a bootstrap server. For 
example, the server at .example should produce a 404 for "foo.not_an_example" 
but if handed "rdap-bootstrap" could then redirect to a more appropriate place.

[JS] Yes, these scenarios make sense. Thanks for the explanation.
